network: How is your setup? Do you know about IP / DHCP and so on?
normally, the network card will be identified correctly, but if you have a small network, i would assume there are static IPs? Then you have to configure it by turning off DHCP and then set up a own, static IP.
Then you have to set DNS and Gateway to the IP of the router. That's it...
Does this help? Ask again if not.
CD-ROM: Do you know about how to mount a drive?
Do you have supermount running?
You could in a console do
and post the output here... (type 'q' to exit).
AND (the better solution since you can learn more...) type
and read and try to understand...
else: google around, search through here....
and if nothing helps, you are welcome to ask again... ;-)
